Magnogen's newest website, v1.4+

After not having time to help with making the website and adding my ideas for it, I chose to merge
all 236 commits (ones making this repository not up-to-date with Magnogen:master) so I have the
newest version of his website and close a pull request because I'm not going to do those tasks on his website.

Magnogen website v1.3.9

Version 1.3 was tagged by Connor on the 5th of July.
I've added the minor version number for some small edits since it.

Release notes for version 1.3:
Added a slideshow to the homepage!
Then removed it again... I really need to make up my mind...
Tried adding the "src" directory, only working for the home page - might fix that soon, lol.
Ha ha - I fixed it! (Thanks for the help, @user-e )
